OK, I gave it a second try, and now everything works. Maybe the patch had not
yet been pushed to the repo at my first attempt? Or another patch was delivered
in the meantime? Somehow unsatisfying, as the situations were identical, I
restored the system to the state of my first attempt from a
Dear list,
I have another question regarding stopping the flowgraph. This time it is
about streaming blocks, no messages involved at all.
My flowgraph looks like this (block A) --byte-- (block B) --byte-- ...
Block A is a byte source that signals EOF at a certain point, lets assume
after

this won't 100% answer your Q's, but perhaps it'll help:

Has anyone developed a work around for replacing gr.multiple_cc() to work on
ARM devices that have to disable NEON in order to install? I have two lines in
gr.ais that keep giving me overflow.
Thanks ahead of time,

The segfault is a different story. Like Josh suggests a backtrace would be
helpful to see exactly what went wrong.
The generic implementation of the rotator function normally takes 5-6
seconds on a typical machine, so the

Hello Gurus,
My duplex system is using only one frequency but different time slot to let
two USRP exchange data. But from the observed receiving waveforms, I found
that the received signal is very high and causes the jitter if the receiver
keeps receiving its own transmitted signal within its own
Hi. I am just beginning to learn how to use gnuradio. I am currently
running Linux 12.04 LTS and installed gnuradio using the script provided by
Marcus Leech.
I tried doing a little simulation in gnuradio-companion using a source and
two wxgui sinks.
The problem is that when i run my simulation,

Hi everyone, I am newbie on gnuradio and I have a question about ofdm
benchmark. If I use benchmark_tx.py and benchmark_rx.py I have a good
performance, (an error rate below 10%).
However, if I only modify the benchmark_tx.py and I add only a
time.sleep(1) between send_pkt(payload) like is
Hi,
This is a common issue with laptop screens and low vertical resolution.
This page explains the window grid positioning:

So if you make one of your wxgui components use 0,0,1,1 and the other
0,1,1,1 they
Hi, again! Thank you both very much for your answers. They were very
helpful.
Have a great day, everybody!
